Question

A standard chromatogram of three dyes (red, blue, and green) is given below. Based on the standard chromatogram analysis and the given chromatography, grams (A, B, C, and D), arrange them in the order of the descriptions given below.

(i) This chromatogram represents a mixture of all three dyes along with an impurity.
(ii) This chromatogram represents a mixture of red and blue dyes.
(iii) This chromatogram represents a mixture of all three dyes.
(iv) This chromatogram represents a mixture of red and green dyes.

  1. CABD
  2. BDAC
  3. ADCB
  4. DBAC

hintHint:

Based on the principle of chromatography.

The correct answer is: BDAC


    A represents a mixture of all three dyes.
    B represents a mixture of all three dyes along with an impurity.
    represents a mixture of red and green dyes.
    D represents a mixture of red and blue dyes.
